How winter affects your pet’s health 

Winter in Ontario can be beautiful, but just like for us, the colder months can bring a unique set of health challenges for our pets. From stiff joints to dry, itchy skin and weakened immune systems, winter can take a toll on both cats and dogs. 

Prevention and awareness are key to keeping pets comfortable, healthy, and happy year-round. Here’s how winter affects your pet’s health and what you can do to support them. 

Joints, stiffness and arthritis 

Cold weather can be especially hard on pets with joint issues. Just like people, dogs and cats may experience increased stiffness, reduced mobility, and discomfort in colder temperatures. Pets with arthritis, past injuries, or age-related joint degeneration are particularly vulnerable. 

Signs: 

• Hesitation to go for walks or climb stairs 

• Slower movement or stiffness after resting 

• Limping or difficulty getting up 

What you can do: 

• Keep walks shorter but more frequent to maintain mobility 

• Consider fitting your dog for a winter coat 

• Provide warm, padded bedding away from drafts 

• Maintain a healthy weight to reduce strain on joints 

• Talk to your veterinarian about joint-support supplements or pain management options 

Dry skin and coat issues 

Winter air tends to be dry, and that dryness can affect your pet’s skin and coat. Indoor heating strips moisture from the air, often leading to flaky skin, itchiness and dull fur. 

Signs: 

• Increased scratching or licking 

• Dandruff or flaky skin 

• Brittle or thinning fur 

What you can do: 

• Limit bathing and use pet-safe moisturizing shampoos 

• Ensure a balanced diet with essential fatty acids 

• Use a humidifier in your home, if possible 

• Always provide fresh water to support hydration 

• Consult a veterinarian as it could be a sign of other underlying health issues 

Immune health during the colder months 

Winter can put additional stress on your pet’s immune system. Less outdoor activity, reduced sunlight, and increased exposure to germs can all play a role. 

What you can do: 

• Keep vaccinations up to date 

• Feed high-quality, nutrient-rich food 

• Encourage safe indoor play to maintain physical and mental health 

• Watch for early signs of illness, such as lethargy or changes in appetite 

• Regular veterinary checkups should be performed to ensure there is no health concerns 

Winter doesn’t have to mean discomfort for your pet. With a little extra attention and proactive care, you can help them stay active, comfortable, and healthy through the colder months. 

If you notice changes in your pet’s mobility, skin, or overall behaviour, it’s always a good idea to consult your veterinarian.  

Together, we can ensure every pet feels safe, supported and cared for no matter the season.
